THE PROCESS OF COATING VITREOUS FILAMENTS FORMED FROM A MOLTEN MASS IN A MELT ZONE, SAID PROCESS COMPRISING THE STEPS OF DRAWING A VITREOUS FILAMENT FROM SAID MELT ZONE THROUGH A FIRST APERTURE IN A DIE, ADVANCING SAID FILAMENT FROM SAID FIRST APERTURE DIRECTLY INTO A BUFFER ZONE, ADVANCING SAID FILAMENT FROM SAID BUFFER ZONE THROUGH A SECOND APERTURE INTO A PLATING ZONE, ADVANCING SAID FILAMENT FROM SAID PLATING ZONE INTO AN EXHAUST ZONE, SAID MELT ZONE, SAID BUFFER ZONE, SAID PLATING ZONE AND SAID EXHAUST ZONE BEING DISPOSED SEQUENTIALLY ALONG A PATH, INTRODUCING AN INERT GAS INTO SAID BUFFER ZONE, INTRODUCING A HEAT DECOMPOSSABLE GASEOUS METAL COMPOUND INTO SAID PLATING ZONE, SAID METAL CARBONYLS, SELECTED FROM THE CLASS CONSISTING OF THE METAL CARBONYLS METAL HALIDES, ORGANOMETALLICS, METAL COMPOUND IN SAID TURES THEREOF, DECOMPOSING SAID METAL COMPOUND IN SAID PLATING ZONE IN THE PRESENCE OF SAID INERT GAS IN THE TEMPERATURE RANGE FROM 100 TO 1,000*C. IN ORDER TO COAT SAID FILAMENT WITH METAL, EXHAUSTING SAID EXHAUST FIGIG-01 ZONE SO THAT THE MINIMUM PRESSURE ALONG SAID PATH IS IN SAID EXHAUST ZONE, SAID SECOND APERTURE BEING LARGER IN EXTENT THAN SAID APERTURE.
